【 摘 要 】

The control degree of the sand body and the coincidence rate of the microphase prediction are statistically analyzed by using the post test well, and the main factors affecting the reservoir description accuracy are analyzed. The effects of the well density, the reservoir plane heterogeneity and the well seismic combination technology on the reservoir description accuracy are qualitatively and quantitatively evaluated, and the sand body changes before and after the well encryption are summarized. This paper clearly points out that two methods are the main way to improve the description accuracy under the condition of well pattern. First, the application of coring wells to deepen the understanding of sand body plane transformation. Second, deepen the well seismic combination reservoir description technology.
